Filing A Roundup Lawsuit In California (2026)

Who Can File a Roundup Lawsuit in California?

To file a Roundup lawsuit in California, you will need to first demonstrate that you were exposed to this product and developed cancer. One of the specific cancers most associated with Roundup is non-Hodgkin lymphoma. A Roundup lawyer can help you understand whether you’re eligible.

Proving Exposure and Causation in Roundup Claims

To show that you were exposed to Roundup, you must present evidence of purchasing the product, like receipts, or of working for a company that used the product.

California Specific Rules, Including Proposition 65 Warnings

In California, manufacturers must place Proposition 65 warnings on all products that contain certain chemicals known to cause cancer, birth defects or other reproductive harm. Glyphosate is on the Proposition 65 warning list.

Companies must also warn workers if they’ve been exposed to these chemicals. Not doing so can lead to failure-to-warn lawsuits.

Where Cases Are Filed in California State and Federal Courts

A California personal injury lawyer can help you decide where to file the case. You will typically do so in the federal multidistrict litigation (MDL) based out of the U.S. District Court for the Northern District of California. If you file an individual case, though, you can do so in courts throughout the state.

As you consider where and how to file your case, keep a few issues in mind. First, the MDL was created to cover cases alleging that Roundup causes non-Hodgkin lymphoma. If you suffered any Roundup side effects other than non-Hodgkin lymphoma, such as leukemia, you cannot file a case as part of the MDL. Instead, you must file an individual lawsuit in either federal or state court.

Second, if you do have non-Hodgkin lymphoma, you can join the MDL by filing in federal court. The benefit of joining the MDL is that your product liability attorney will have access to evidence and experts used by other plaintiffs’ attorneys in the MDL.

Third, whether you file in state or federal court, the same product liability laws will apply, including the product liability statute of limitations California uses.

Deadlines to File a Roundup Claim in California

If you’re part of an MDL case, the statute of limitations can vary. If you’re filing individually, you may only have two years from when you discovered you had developed cancer from exposure to Roundup.

Compensation Available in California Roundup Cases

In a Roundup lawsuit in California, you can seek compensation for your medical expenses, lost wages and the emotional and physical suffering you experienced.

On February 17, 2026, Bayer proposed a global settlement to resolve all cases where the plaintiff suffered non-Hodgkin lymphoma. According to the company’s press release, it would create a settlement fund of $7.25 billion. It would cover current and future claims against the company.

You are not required to accept the settlement. You can file a lawsuit and present your case to a jury. However, this option carries a few risks. First, litigation takes time. You might not reach trial for a year or longer. Second, you might lose at trial and receive nothing.

Finally, Bayer has an appeal before the U.S. Supreme Court arguing that it cannot be sued because it complied with pesticide labeling laws. If the company wins this appeal, all pending cases may be dismissed.

How a California Product Liability Lawyer Builds Your Case

A product liability lawyer can gather evidence, calculate the full losses you suffered and negotiate with insurers to obtain a fair settlement. When that’s not possible, they can also take your case to trial.
